Walk to Totem Park

The kids and I braved the wind to walk down to the park and see what might be around. I thought the gusts of wind pushing spray across the bay was particularly interesting.

19 December Photos: Loons

matt goff — Thu, 20 Dec 2007 07:27:13 +0000

I was able to get photos of a Pacific and Common Loon swimming near each other, unfortunately they were not too near me and the light was a bit harsh.

Loon Identification Update

matt goff — Sun, 11 Nov 2007 06:01:25 +0000

I have had a few responses to the Loon Identification post I made a couple of days ago. One of them pointed out that there is a discussion of Loons in the Peterson Field Guide to Advanced Birding by Kenn Kaufman. I have had the book for some time, but did not think to look in it, so that was helpful. I also appreciate the other responses I have had, as the discussion helped clarify for me the difficulties I am having. I now think that all but one of the birds I am having trouble with are all Common Loons (perhaps all first winter, but I’m not sure). The other bird is hard to be certain about due to the poor quality of the photo, but I’m leaning toward Red-necked Loon due to the relatively small bill and the general lack of pattern on its neck.

Below is one photo of each of the other loons in question. I have arranged them from the most Pacific Loon-like to the least Pacific Loon-like, to my eyes. (Numberings are from the previous post, look there to see additional photos of some of these loons.)

(Click thumbnails for larger versions.)

(Bird #1)

Loon observed at Starrigavan 14 December 2004.

(Bird #5 and #6; there were two at the time, but I’m not sure I photographed both)

Common(?) Loon observed 12 December 2006 outside Crescent Harbor breakwater. Seen with Common Loon.

(Bird #2)

This Loon was observed at Eliason Harbor 6 November 2006.

(Bird #3)

I am not entirely certain about this identification. The bird seemed less bulky than many Common Loons. Perhaps it's a first year bird? Observed 16 January 2007 at Eliason Harbor.

(Bird #4)

Loon observed 12 December 2005 in Crescent Harbor breakwater.

(Bird #8)

Common(?) Loon observed 27 October 2006 while kayaking at north end of channel.

It seems to me that the first five pictures above show something of a continuum of patterning on the neck. However, it also seems like lighting, posture, and positioning play a significant role in the apparent patterning (or lack thereof) on the neck. To me, the sixth bird looks signficantly different than the first five, but it’s worth noting that it’s also the only one without its head/neck extended up rather then folded down a bit.

It’s also worth noting the following picture of Bird #4, which look far more Common Loon-like.

Loon observed 12 December 2005 in Crescent Harbor.

Upon realizing that I had misplaced the third picture of Bird #4 (the one that’s in the list above) and it actually belonged with these two, I came to think that probably all of the birds were Common Loons since the third picture fit into the continuum of birds that looked a little unusual for Common Loons and had elements suggestive of Pacific Loons, but also, in different postures, looked very much like a Common Loon.

Of course, I could be wrong about all of this, but I like to think I’m on the right track. Hopefully someone will set me straight, if I’m not.

Questions that remain for me are:

How variable is the neck pattern in Common Loons? Does the first bird, which seems to have no neck pattern at all, but otherwise looks very much like the other birds, fit within this variation?

How variable is the amount of white around the eye in Common and Pacific Loons? Pictures I have of birds that are clearly Pacific Loons (scroll to bottom for photos) seem to show white around the eye, though the field guides I’ve looked at suggest there is not any. The birds pictured above do not have as much white as other birds I have taken pictures of that are clearly Common Loons (scroll to bottom for photos), and less than the field guides I’ve looked at seem to suggest they should have.

Is it unusual for a Common Loon to show a chin strap, as Bird #8 seems to?

Loon Identification

matt goff — Fri, 09 Nov 2007 08:15:03 +0000

It’s the time of year that loons are most easily observed around Sitka, and I was recently reminded that I have pictures of several different loons taken over the last three years that I have had a hard time figuring out. I’ve got my best guesses for most/all of them, but for each there is some question that remains. I suspect most of the difficulty I’m having is due to variation in characters (both between individuals, and within the same individual due to difference in posture) that I do not have a good handle on. I imagine some (all?) of them are fairly straightforward to someone with more loon experience, so I’m hoping I might be able to get a little help from birders with more knowledge. I would appreciate any comments on identifications and/or the range of variation in the character traits that are causing me trouble.

Loon comparison

Loon observed at Starrigavan 14 December 2004.

Common(?) Loon observed 12 December 2006 outside Crescent Harbor breakwater. Seen with Common Loon.

Update: For an idea of the trouble I’ve had, these two photos were taken about a year apart. I have tended to think of the first (Bird #1) as a Pacific Loon and the second (Bird #5 or #6) as a Common Loon. Until today, I have never thought to compare them. Now I see these are close enough that they could almost be the same bird. Certainly it seems like whatever I think one is, the other must be also. I think this analysis also applies to Bird #2 and Bird #3, as well. It seems that if I can get an identification for this form that keeps showing up, I would have the most of the problem birds I see figured out (the other ones are more problematic due to distance/poor conditions for photography).

Pacific(?) Loon (Bird #1)

Loon observed at Starrigavan 14 December 2004.

This loon was the first I ever took pictures of, back on 14 December 2004. I have changed my mind about whether it was a Pacific Loon or not several times over the time since, though most often I have considered it a Pacific Loon. What inclines me toward Pacific Loon is that it seems to have the clean line between white and gray on the neck and it’s not as bulky as I tend to think of Common Loons being. On the other hand, the bill seems more bulky than I would expect for a Pacific Loon, it seems to have white around the eye, and there’s no hint of a chinstrap. However, it looks even less like a Common Loon.

Common(?) Loon (Bird #2)

This Loon was observed at Eliason Harbor 6 November 2006.

Snowy weather does not lend itself to optimal photographic conditions, and this photo reflects that. However, I hope the bird can be seen well enough for identification purposes. My best guess is that this is a Common Loon, but I am troubled by the apparent lack of white partial collar and the seemingly short/small bill. On the other hand, the line between white and gray on the neck does not seem as clean as it should be for a Pacific Loon, and the bill seems a bit more robust than I would expect on a Pacific Loon. This bird was observed in early November 2006.

Common(?) Loon (Bird #3)

I am not entirely certain about this identification. The bird seemed less bulky than many Common Loons. Perhaps it's a first year bird? Observed 16 January 2007 at Eliason Harbor.

This may be the same bird as the previous one, though this picture was taken 16 January 2007. The bill seems more reminiscent of a Common Loon, though it does not seem to have the bulk I expect of a Common Loon. To my eyes it does not appear to have a partial white collar, nor does it have much white around the eye (as would be expected with a Common Loon). While bulk/size and lack of white around the eye seems consistent with Pacific Loon, the bill does not, nor does the contrast/line between light and dark on the neck.

Common(?) Loon (Bird #4)

Loon observed 12 December 2005 in Crescent Harbor.

Loon observed 12 December 2005 in Crescent Harbor breakwater.

This loon, photographed in the south corner of Crescent Harbor 12 December 2005, seemed to me a Common Loon. I still lean pretty hard toward Common Loon, as it’s got the bulk and the contrast/line between the light and dark of the neck seems more consistent with a Common Loon. On the other hand, the bill seems a little short and there is no white above the eye (as would be expected on a Common Loon). Update: Looking at the third picture, it’s apparent there is some white above the eye. I had forgotten the third photo was of this bird (rather than the ones taken the same day outside the harbor) until going back through the pictures and double checking my original notes on it.

Common(?) Loons (Bird #5 and #6)

Loon observed 12 December 2005 outside Crescent Harbor breakwater.

Common(?) Loon observed 12 December 2006 outside Crescent Harbor breakwater. Seen with Common Loon.

Common Loon observed 12 December 2005 outside Crescent Harbor breakwater.

These are pictures of two birds that seemed to be swimming together near Crescent Harbor breakwater on 12 December 2005. I think they are the same species. I’m leaning toward Common Loons as they have some white around the eye and the bill seems fairly bulky. However, they seem a little less bulky than I would expect (compare with the bird above, though maybe things like the apparent thickness of neck have more to do with posture than anything else). Also there seems to be a hint of a chinstrap and there does not appear to be a partial white collar (though it’s still not as clean a line between light and dark as I might expect on a Pacific Loon).

Update: Now that I have compared one of these photos with one I am thinking of as a Pacific Loon (see above), I’m a little more inclined to think these are Pacific Loons.

Pacific(?) Loon (Bird #7)

This Red-throated Loon was observed while kayaking in Eastern Channel on 27 October 2006.

I only saw this loon briefly from a distance while I was kayaking in late October 2006. My current thinking is that it’s a Pacific Loon, but I also wonder about Red-throated Loon. I’m not sure that I can rule it out. Given the poor quality of this photo, perhaps there cannot be a definitive answer, but I figure it’s worth a try.

Common(?) Loon (Bird #8)

Common(?) Loon observed 27 October 2006 while kayaking at north end of channel.

Seems to have the bulk of a Common Loon. The bill looks a little short, there’s a chinstrap, white edging to feathers on its back seems unusual, and I don’t really see a white collar. Seen 27 October 2006.

1 January Photos: Eliason Harbor

matt goff — Tue, 02 Jan 2007 05:00:03 +0000

A stormy day to start the year. These photos are from Eliason Harbor and underneath O’Connell Bridge.

[Show slideshow]

These two Pacific Loons were actively diving among the fingers of the dock. The bird in front seems to have a slightly deformed (crossed) bill.

The boats in Eliason Harbor were swaying back and forth in the strong winds. If you look close, it is possible to see a wave splashing up over the side of the dock.

The chinstrap seen on the right side bird is an indication that it is a Pacific Loon. Observed 1 Jan 2007.
